Oscar Wilde, a great British writer, once admitted to spending an entire morning removing a comma from a poem. Asked if that was all he had done, Wilde replied, “By no means: on mature reflection, I put back the comma.” If a great writer like Oscar Wilde had difficulty in deciding where and when to use a comma, what chance have the rest of us got? In this lesson I will teach you about the history of the comma and about how to use it. You will learn about clauses, ambiguity, the Oxford comma, question tags, coordinating conjunctions, coordinate adjectives, dates, and more.
